Title: Improvements in Apparatus for Regulating the Electric Lights on Theatre Stages.
Filed: 1900-02-06
Granted: 1900-04-07
Abstract: 2356. Siemens Bros. & Co., [Siemens & Halske Aktiengesellschaft]. Feb. 6. Rheostats.-An apparatus, for controlling the lighting of a theatre stage by groups of lamps, consists of rheostats v, in circuit with the groups, and separately connected by weighted cords with sector-levers c, which are mounted on a single shaft w so that each lever, rheostat, and group of lamps may be separately regulated, or the whole may be varied together, to either increase or diminish the light, commencing with the parts in any positions, by turning the shaft with all the levers by a hand-wheel and toothed gearing, not shown. For this purpose, each sector lever is loose on the shaft but can be engaged with a toothed wheel m, fixed thereon, by pawls k pressed inward by springs f. The pawls can be disengaged by inserting between them a cam h, supported on the lever by a sliding-rod d, which is provided with a spring pressing it inward, and a handle e and a pin d<1> for moving and holding it out. A pointer on each lever indicates its position on a stationary scale z. When the shaft w is turned so that a lever reaches an extreme position, the driving- pawl comes in contact with a spring stop a, and is disengaged from the toothed wheel, so that the shaft may continue to turn; an arm of a spring m<1> carried frictionally on the shaft then lifts the second pawl from the toothed wheel, to prevent noise by the passage of the teeth under it.

Title: Improvements in Switching Apparatus for Electric Circuits.
Inventor: DUDDELL WILLIAM DU BOIS
Filed: 1901-03-07
Granted: 1902-02-27
Abstract: 4820. Duddell, W. du B., and Mather, T. March 7. Switches.-In connecting and disconnecting conductors, injurious transient rise of pressure is minimized by suitably introducing a non-inductive resistance. One method. as shown in Fig. 1 for connecting a cable C, C<1> to generator terminals G, G', consists in interposing a resistance, such as a liquid resistance in vessels J, J', between the terminals. The resistance is cut out by lowering the plungers P, P', and introduced when the circuit is to be opened by raising them. In a modified arrangement, two pairs of vessels, with the plungers rigidly connected in pairs, are employed. Another method is shown in Fig. 3. The generator terminals are connected by a non- inductive resistance, and the cable terminals C, C<1> are connected to the resistance close together and then moved nearer to the terminals G, G', the shunt resistance being finally opened between carbon contacts. Fig. 4 shows another arrangement. One terminal G of the generator and one cable C are connected, and the other terminal G<1> is connected to the plunger P<1>, just touching the resistance ; the other plunger P' is immersed in the liquid, and is raised until it makes contact with P<1>. Various other arrangements are described for manipulating the resistances. In Fig. 6, the terminals C. G are connected to the contact vessel J<1>, the cable C' to both vessels J<2>, J<3>, and the other terminal G' to the vessel J'. In connecting up, the first movement of the cam shaft allows the plungers P', P<2> to descend, as shown, and vent the plungers P<3>, P<4>, thus gradually increasing the pressure in the cables C, C', and finally the plungers P', P<2> are raised, cutting out the shunt to the cables. In disconnecting the cables, the operations are reversed. These methods may be used in connection with cut-outs, the switches being operated by suitable relay arrangements.

Title: Improvements relating to Feed-water Regulators for Use in connection with Steam-generators.
Inventor: FLINN RICHARD JOSEPH
Filed: 1901-04-02
Granted: 1901-06-08
Abstract: 6893. Flinn, R. J. April 2. Feedwater, supplying and controlling.-Relates to means for maintaining the water in a boiler at a practically constant level, applicable more especially to the boilers of motor vehicles. According to the arrangement shown diagrammatically in Fig. 1, water from a main supply tank 2 is supplied by the pump 14 to an auxiliary elevated tank 3, which communicates with the boiler 1 by two separate channels 4, 7 shown combined in a single pipe. The channel 4 terminates below at a lower level than the channel 7, and opens into the tank 3 at 5, while the channel 7 opens into the tank 3 at the top at 8. The pump 14 is constructed to supply slightly more than the maximum quantity of water required, the surplus overflowing at 21 and passing through the steam trap 23 to the tank 2. The apparatus acts on the bird-fountain principle, a pressure of steam being maintained in the tank 3 which is less than that in the boiler by the amount due to the height of the column of water in the channel 7. All the while the level of water in the boiler is above the opening of the channel 7, a circulation of water is maintained between the boiler and the tank ; but, as soon as the level falls below the opening in the channel 7, steam passes into the tank, and water falls through the channel 4 until the level is raised again. In a modified form of the apparatus, the channels 4, 7 are constructed as separate pipes, the latter being made adjustable in length. Fig. 4 shows another arrangement, in which the tank 3 constitutes the boiler. In this case, the pump 14 constantly supplies an excess of water, which is returned by the overflow and through the steam trap to the tank 2.
